CR5 register
SMPSLVL | SMPSLVL[3:0] SMPS Output Level Voltage Selection Select the SMPS output voltage with a granularity of 50mV. Default = ‘0100’ (1.4V) Vout = 1.2 + 0.05*SMPSOUT (V) |
SMPSBOMSEL | SMPSBOMSEL: SMPS BOM Selection: 0 (B_0x0): BOM1 1 (B_0x1): BOM2 (default) 2 (B_0x2): BOM3 3 (B_0x3): n/a |
SMPSFRDY | SMPSFB Force ready check When this bit is set, the SMPS FSM will consider the SMPS ready . 0 (B_0x0): no effect (by default) 1 (B_0x1): SMPS is considered READY |
SMPSLPOPEN | SMPSLPOPEN: In Low Power mode SMPS is in OPEN mode (instead of PRECHARGE mode). When this bit is set, when the chip is in Low power mode the SMPS regulator will be disabled (HZ) Documentation needed. 0 (B_0x0): in Low Power mode, SMPS is in PRECHARGE, output is connected to VDDIO. 1 (B_0x1): in Low Power mode, SMPS is disabled, output is floating |
SMPSFBYP | SMPSFB Force SMPS Regulator in bypass mode When this bit is set, the SMPS regulator will be forced to operate in precharge mode. the actual state of SMPS can be observed thanks to the replica SR2.SMPSBYPR. 0 (B_0x0): no effect (by default) 1 (B_0x1): SMPS is disabled and bypassed (ENABLE_3V3=0 and PRECHARGE_3V3=1) |
NOSMPS | NOSMPS: No SMPS Mode When this bit is set, the SMPS regulator will be disabled. Note that this configuration should be used only when SMPS_FB pad is directly connected to VBATT or Vext, without L/C BOM. 0 (B_0x0): No effect, SMPS is enabled. 1 (B_0x1): SMPS is disabled; |
SMPS_ENA_DCM | SMPS_ENA_DCM: enable discontinuous conduction mode 0 (B_0x0): disable 1 (B_0x1): enable |
CLKDETR_DISABLE | CLKDETR_DISABLE: disable SMPS clock detection The SMPS clock detection enables an automatic SMPS bypass switching in case of unwanted loss of SMPS clock. 0 (B_0x0): SMPS clock detection enabled (default) 1 (B_0x1): SMPS clock detection disabled |
SMPS_PRECH_CUR_SEL | SMPS_PRECH_CUR_SEL[1:0] Selection for SMPS PRECHARGE limit current 0 (B_0x0): 2.5mA 1 (B_0x1): 5mA 2 (B_0x2): 10mA 3 (B_0x3): 20mA (default) |
